> Currently, Vertex implements Writable, meaning that we depend on the user (except for the default implementation) on the way the graph is serialised and deserialized. This means we cannot do certain optimisations, and the user can actually add additional stuff to Vertex more than Value, Id, Edges and halt state. By removing this possibility (or allowing them to extend a default implementation) we take control of this.
